Description

Technical Field

[0001] The utility model relates to the technical field of door and window components, in particular to a one-way locking hollow glass gasket with adjustable width. Background Art

[0002] Insulating glass is an important component of door and window products. Due to limitations in processing technology and installation conditions, the current installation of insulating glass basically adopts the glass gasket installation method. The glass groove widths of door and window frames and sash profiles of different types and series are different. The same door and window product can also adapt to a wide range of insulating glass thicknesses. This leads to the need to prepare glass gaskets of different widths to adapt to insulating glass of different thicknesses during the installation of insulating glass. Because the thickness of insulating glass often varies in millimeters, the width of ordinary gaskets deviates from the thickness of insulating glass. If the gasket width is larger, it may affect the installation of glass pressure strip profiles; if the gasket width is smaller, the deadweight of the insulating glass is transferred to the profile through the gasket, and the force point is offset, resulting in excessive local force on the profile and affecting the structural strength.

[0041] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0042] The utility model also has the following implementation methods based on the above:

[0043] In a further embodiment of the utility model, the main gasket is composed of a main gasket base 1 and a main gasket top cover 2. The basic principle is that the patented gasket can be adjusted in width with an interval of 2 mm according to the thickness of the insulating glass, and the adjustment range is large. It has a one-way self-locking function to prevent the gasket width from changing when the insulating glass is installed. At the same time, the supporting feet of the main gasket and the sliding gasket 3 are evenly divided to ensure the uniform transmission of the deadweight of the insulating glass. The gasket is made of polypropylene plastic (PP) and has a certain deformation ability.

[0044] In a further embodiment of the utility model, the assembly method is: 1. Place the sliding gasket 3 on the main gasket base 1, and ensure that the ratchet 33 on the lower side of the ratchet arm 32 is inserted into the one-way ratchet track 13; 2. Align the positioning bolt 12 on the main gasket base 1 with the positioning hole 22 on the main gasket top cover 2, and press the main gasket base 1 and the main gasket top cover 2.

[0045] In a further embodiment of the utility model, the method of use is as follows: the sliding gasket 3 is pulled outwardly, and the one-way ratchet track of the main gasket base 1 pushes the ratchet arm 32 upward. Every 2 mm of movement, the ratchet arm 32 re-engages with the one-way ratchet track 13 and makes a "click" sound. The current width of the gasket can be determined from the scale mark 35 on the side of the sliding gasket 3. The sliding gasket 3 is continuously pulled to the required gasket width, and the gasket is placed in the use position for use. At this time, the ratchet arm 32 is locked by the one-way ratchet track 13, and the sliding gasket 3 cannot move inward.

[0046] In a further embodiment of the utility model, if the sliding gasket 3 is pulled beyond the required width or the gasket is to be reused, a flat-head screwdriver or a similar tool can be used to insert the flat-head screwdriver into the unlocking hole 34 and then lift the ratchet arm 32. At this time, the sliding gasket 3 can be completely pushed inward into the main gasket to restore the initial state.

[0047] In a further embodiment of the utility model, the structural principle is as follows: the unidirectional movement of the gasket is mainly achieved by the engagement of the ratchet arm 32 with the unidirectional ratchet track 13. The width of the ratchet 33 is 2 mm, one side is vertical, and the other side is inclined at 45 degrees; the ratchet of each unit in the unidirectional ratchet track 13 is axially symmetrical with the ratchet 33, with a width of 2 mm, one side is inclined at 45 degrees, and the other side is vertical. When the ratchet arm 32 moves outward with the sliding gasket 3, the ratchet 33 is squeezed upward by the 45-degree inclined slope of the first ratchet of the unidirectional ratchet track 13, and the root of the ratchet arm 32 is deformed. After moving a distance of 2 mm, the ratchet 33 passes the junction of the first and second ratchet teeth. At this time, the root deformation of the ratchet arm 32 is restored, and the ratchet 33 falls into the gap of the second ratchet tooth. At this time, the vertical side wall of the ratchet contacts the side wall of the ratchet, and the gasket is in a unidirectional locked state.

[0048] In a further embodiment of the present invention, the one-way locking is unlocked mainly by tilting up the ratchet arm 32 through the unlocking hole 34 to disengage the ratchet 33 from the one-way ratchet track 13 .

[0049] In a further embodiment of the utility model, the structural features are: a large adjustable range; easy assembly; and uniform structural force.

[0050] In a further embodiment of the utility model, the overall width of the hollow glass gasket of the utility model is adjustable and is suitable for door and window products of different sizes. The sliding gasket 3 is pulled outward to adapt to the spacing of the hollow glass. Every time it moves 2 mm, the ratchet arm 32 re-engages with the one-way ratchet track 13 and makes a "click" sound. The adjustable range is large and is suitable for hollow glass of different thicknesses.

[0051] In a further embodiment of the utility model, the hollow glass gasket is composed of a main gasket and a sliding gasket 3, has a simple structure, and is easy to assemble. A scale mark 35 is provided on the side of the sliding gasket 3, and the width of the gasket can be known by observing the scale mark 35.

[0052] In a further embodiment of the utility model, an unlocking hole 34 is provided at the front end of the ratchet arm 32. After a straight head is inserted into the unlocking hole 34, the ratchet arm 32 is tilted up, and the sliding gasket 3 can be completely pushed inward into the main gasket to restore the initial state.

[0053] In a further embodiment of the utility model, a plurality of first strip grooves are provided on the upper surface of the supporting foot 31, and a plurality of second strip grooves are provided on the lower surface of the supporting foot 31. Each first rectangular plate is located in a first strip groove, and each second rectangular plate is located in a second strip groove. The top and bottom surfaces of the supporting foot 31 are limited by the plurality of first rectangular plates and the plurality of second rectangular plates, and the structure is evenly stressed, thereby ensuring the sliding direction of the sliding gasket 3 in the main gasket.

[0054] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
